“My thoughts are with the families and friends of the victims of the horrific stampede at a football stadium in Indonesia,” Bach wrote on social media.
After the match between "Arema" and "Persebaia" there were riots, as a result of a stampede, 174 people died.
The fight in the stands began after thousands of fans ran onto the field after Arema's defeat.
The police used tear gas in the stands, which provoked panic among the fans.
Most of them were trampled to death as other fans tried to leave the stadium, according to a health ministry spokesman.
Earlier, Indonesian President Joko Widodo ordered an investigation into the incident.
